After looking around at what is available in the way of a rear disc setup I came up with this, these will be fitted onto duel sport buggies
This is the parts list
Disc's are 914 Porsche 4 stud
Hubs are 1500 Beetle or Supabug cut down to fit inside the disc and a 2. mm spigot machined on the face to centre the disc
Calipers I am useing are VW Mk4 from a Passat--Beetle--Golf--Jetta (around 99-2005) there are some minor differance's between them, the carriers are from a Passat, the Mk 3 might work also but I think they are steel, all feature an E-brake
Carrier brackets are billet alloy available from Sharpbuilt
I should have the first set fitted up to my Limo over the weekend

Thank you very much for posting these pictures/info!
I want the same setup on my beetle, but I was worrying about the Carrier brackets.

I can't find them on their website. Could you tell me how much they cost? _________________ homepage

I literaly just got back from the machine shop. I was going to have him turn by rear drums down so that they could be used as hubs. He didn't seem to confident about it, plus he seemed a little expensive. $80. Is that price right, or should I keep shopping?
I have a set of rotors and calipers from a Datsun 280zx. They have the parking brake intregated into the caliper.
Mark at Blind Chicken shows a similar setup...http://www.blindchickenracing.com/How_to/280Zbrakes/280zbrakes.htm
I will have to make the caliper bracket. |

The brackets are $125 pr--just e-mail them for a price
$80 sounds a lot I only paid around $30 for a pr
A few guys are going there own disc conversion though useing a welded caliper bracket--here is Aus you if you want to put disc brakes on any car they have to be a one piece non welded bracket |

dunelimo what's the go with ADR approval on the bracket? Does it need some sort of engineering approval because it's not an O.E. bracket? _________________ Reversed gears for Subaru Transmissions

If you go from drum brakes to disc brakes the whole setup will be inspected not only the bracket---but the bracket has to be one piece no welding |

Looks great, tip of the hat to you for making it work. I really like the idea of using common easy to find and adapt parts for upgrading.
Disc brakes are superior in so many ways. Is there any performance advantage you are seeking through this adaptation over the kit brakes? Looks to be roughly equivalent in price to kits I've seen when you factor in machineing, sourcing, and assembly time and effort. Are you doing anything for an emergency brake?
Good job. _________________ Gary

The 2 piece 914 disc set up is stronger than the aftermarket I piece, they are also cheaper to purchase, the billet bracket is the strongest compared to the one piece non welded bracket or cast ones (I cannot use welded brackets)
I am saving more than a 1/3 in total over the price of an aftermarket empi kit that has a stamped steel bracket and a I piece disc and I am getting a much stronger setup for offroad use, the calipers have an e-brake that I will use |

I believe that is the standard rear disc set-up and caliper sold by CB performance in their street kits (but with a cast bracket?). I wanted to use a simple arrangement like that but the weight was excessive (for my over-excessive application!). I later found about an all aluminum Golf rear caliper that could possibly be substituted for the iron one - but also read about locking-up issues with it? Still doesn't alleviate the weight of the iron slider bracket.
A single caliper (doing both brake and e-brake jobs) sure makes life easier!
I eventually settled on one caliper for each job....

your caliper bracket is the same as I make, but only for swing use, IRS is weld on...
for rotors mid 80 mercedes rears, there thicher than 914's,, calipers are front floating Honda's.. if you want parking brake , then rear honda but from a SI model
Now days, I have seen some places that will sell just the aftermarket caliper mounting brackets |

I could not find any to work with the Mk 4 caliper and 914 disc, but now there is another over the counter bracket that can be used so you can get some disc brakes out back |

The setup is all installed on my Limo, had to wait for some soft lines and hand brake cables to complete the install

That's looking good Dune Limo!!
I ordered them from Mike too, two weeks ago.
And this package was delivered today here:
I am very happy with it, it looks great and they are light too!
And delivered in two weeks from Australia to the Netherlands is excellent too!
What kind of (hand) brake lines did you use? _________________ homepage

If you don't mind my asking,who is "Mike" how do I contact him and might he make a similar bracket I need for another application. (Last question obviously best asked "mike" himself). _________________ "We buy things we don't need,..with money we don't have,...to impress people we don't even like". |

Mike, otherwise known as Dunelimo, is the owner of Sharpbuilt, they are an Australian company based at Toowoomba in Queensland.
Here is the web site.
http://www.sharpbuilt.com.au/dunebug.htm
there should be an email address somewhere there.
Or just send a PM to "Dunelimo" |

In a away you are right, they are two people.
There's Mike, the mild mannered buggy builder from Toowoomba
And then there's Dune limo, the maniac buggy driver we sometime let loose down at the Stockton sand dunes.
Take at look at some of his vids in his web site, my favorite is Australia Day 2007, I just love the last scene going off into the sunset. |
